SUPPORT 'AND mn'rnon or maxmosamn Oliver E. De Bidder, Rochester, N. Y. Application luly 5,-1933,8erlal No. 679,119 Claims. (01. 12-142 The invention relates to a shoe or the turned shoe or the stuck on shoe type and method of making the same.

The object of the present inventionis to incor- 5 porate in a shoe, such as a turned shoe or a Sbicca shoe of Patent No. 1,902,725, a support for the metatarsal jointas well as the main arch of the foot and to enable a shank piece divided from the single sole and extending from the heel to the metatarsal joint to' be molded on a last constitut ing the female member of the mold and on which \the shoe is lasted so that it will be unnecessary for the shank piece after being molded, to be removed from the last, and the metatarsal support by being incorporated in the shoe in the manu- Iacture thereof will always remain in proper'position. Heretofore attempts have been made aftera shoe of -the said type has been constructed to apply to such a shoe a metatarsal supportasan auxilia y part or accessory secured to the completed shoe in an effort to lit the requirements of the wearer. Such attempts have been unsatisfactory because shoes have always been made with a flat. bottom and owing to' construction dif ficulties when ashoe or insole is tampered with it loses its true contour or shape around the edges-and a shoe to which such an auxiliary device has been applied would not have its true form. All shoes have to be made over a last and any construction which interferes with the bottom !shape of that last produces a malformation of the shoe. The ideal-of many shoe manufacturers for years has been to try and mold the conformation of the bottom of the foot into a shoe which would ing' in a shoe. By this molding process, such as is described in Patent No. 1,4'l9,899, granted to me January'8, 1924, the molding of an inner sole' was accomplished by using a last as the female member of the mold. By employing the last mold "and metatarsal support in the shank piece of a single sole shoe, a shoe having a metatarsal support is produced without distorting the insole or interior of the metatarsal pport is applied as a separate piece or accessory to the shoe after the lasting of the same has been completed. 7 V All shoes to be practical must have a flat bottom on the outside for if any protrusions were on the bottom of the shoe they'would simply wear If a single sole of the ordinary construction used in the aforesaid type of shoes were'molded on a last there would be formed on the bottom of the single sole projections, which would soon wear save the person from doing what is'called break-- shoe as is the .case'where the.

off and destroy'the metatarsal supporting charactor of such a single sole. By the present method the shank piece divided from the single sole blank and constituting an inner sole or inner shoes a foot print in leather and will obviate the necessity of breaking in a shoe.

With these and other objects in view, the invention consists in the. construction "and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction, within the scope of the claims, may' be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

of the same.

the aforesaid patent and provided in its bottom 10 or lower sole receiving face with a depression 2 adapted to mold in the front end of a shank piece 3 a raised or arched portion 4 toform a metatarsal support or a support for the metatarsal joint of the foot of the wearer. The shank piece 3 which is divided from an outer sole 5 may be formed integral with s rand 6, as illustrated in Figs. 2 and 3 of the drawings, but the said last 1 may be used for molding a metatarsal support 7 in a shank piece 8 without a rand, as illustrated in Figs. 9 to 12 inclusive of the drawings, when the single sole shoe consists only of a single sole and a shank piece.

The rand which is formed integral with the shank piece is partially split from the same, as clearly illustrated in Fig. 2 of the drawings, and the partial splitting of the rand provides a free frontend or flap 3" for the shank piece to enable the metatarsal support to be molded therein.

The shank piece 3 which extends from the heel to the metatarsal joint of the foot is provided with the free front end or flap 3'' of spatulate formation which is arched by the mold to .form the metatarsal support 4. The shank piece which is moistened for molding is secured to the 18st in the usual manner and a resilient filler 9 of any suitable material is arranged below the arched metatarsal support of the spatulate front end of the shank piece to retain the support in its rounded protruding shape and. enable they 40 outer sole to present a fiat lower face. The pad or fliler which is secured in place by cement has a rounded upper face and a flat lower face, the

' upper face being curved both longitudinally and transversely of the shoe. 45 After the resilient pad or filler is placed in position the rand 6 is moved from the folded back position illustrated in Fig. 2 of the drawings, to its normal or proper position on the front portion of the last, as illustrated in Fig. 3 of the drawing.

'50 and the inner sole or inner section of the single always remain in proper position.

Also by the formation of the metatarsal support in the shank piece during the construction of the shoe the form or contour of the shoe at the edges of the sole is not altered or in any wise-affected as is the case when'aftera shoe is constructed a metatarsal support is applied to the shoe as-an accessory or as an attachment.

, In the lasting of the shoe the upper and the inner and outer soles are secured together by 70 cementing, but any other suitable means may,

of course, be employed as will be readily understood. A complementary insole-outsole combination is made from a single sole blank without any waste.

7 The shoe having the shank piece and the integral rand divided from the outer sole and the method of forming the same are illustrated in Figs. 1 to 8 inclusive of the drawings. The shoe having the inner sole consisting solely of the shank piece 8 divided from the outer sole 11 is illustrated in Figs. 9 to 12 inclusive of the drawings. The shank piece 8 which. constitutes the inner soleis molded on the last 1 and a filler or pad 12 is placed between the metatarsal support 7 and the outer sole to preserve the configuration of the arched metatarsal support 7 of the shank piece 8. The shank piece 8 is molded as heretofore. described in accordance with the method explained in the aforesaid patent and the outer sole 11 with its reduced portion 13 and. the shank piece 8 constitute a single sole. In'

the lasting of the shoe the upper 14 is lasted around the shank piece 8 and the latter constitutes a portion'of the shoe and is incorporated in the same during the construction of the shoe and as it is not removed from the last 1 on which the shoe is lasted it will by being incorporated in the shoe as a structural portion thereof, always maintain the metatarsal support in proper position.

The pad or filler is of sponge rubber, or any other suitable material may, of course, be employed, and the last 1 having depressions or tapered concavities of various sizes and shapes may be provided to form a metatarsal support of the desired sizeand curvature both longitudinally and transversely of the shoe. Irrespective of the length and width of the single sole of the shoe, the metatarsal pad may be I properly positioned with relation to the sole of theshoeandtheshankofleather because'of Blading, that is, because of various sizesof soles and shanks. For instance, in a size 5 the sole and shank would be longer than the sole and shank of anumber, 4 shoe. The metatarsal support which is formed by molding the shank piece at the spatulate front end thereof is curved both longitudinally and transversely of the shoe and depressions are formed at the sides of the raised protrusion or portion which constitutes the metatarsal support and a shoe provided with a metatarsal support has the same in, proper position and is partially if not wholly broken in and does not require the breaking in of a single sole shoe as is necessary with single sole shoes of the ordinary construction.

What iaiblaimed is 1. A shoe having a shank piece complemental .to the sole of said shoe and extending from the heel to the ball and having a spatulate front end provided .with a molded, arched metatarsal sup porting portion, and a rand also complemental to the sole and connected with the shank piece in rear of the spatulate front end thereof.

2. A shoe having a shank piece complemental to the sole of said shoe and extending from the heel to the ball and having a spatulate front end provided with a molded arched metatarsalsupporting portion and a rand also complemental to the sole and connected with the shank piece in rear of the spatulate front end thereof. I g

3. The method of making a shoe with a shank piecehaving a rand extension and a flap at its front end which consists in securing the shank piece to a last havin'ga depression, and molding in the free front end portion of the shank piece a metatarsal support by means of the said depression, and lasting an upper to-the shank piece and the ramhwithou't removing the same from the last to incorporate the shank piece tion thereof;

4. The method of making a shoe with a shank piece having a rand extension. and a flap 'portion at its front end which consists in securing the shank piece to a last having a depression and molding in the free front end portion of the shankpiece a metatarsal support by means of the said depression, inserting a resilient pad beneaththe metatarsal supporting portion of the front end of the shank piece between the latter and the rand, and lasting an upper to the shank piece and the rand without remoiring the saine from the last-to incorporate the shank piece and the rand in the shoe during the construction thereof.

5. A shoe of the class described including a shank piece having anintegral front flap and provided with an integral rand extension connected'with the shank piece at the inner end of the front flap, a cushion arranged between the front flap and the inner portion of the rand extension, and a complementary outer sole fit- 10 ting the shank piece and the rand extension.
